Sentences with phrase «of radiosonde observations»

Although modern remote sensing by satellites, aircraft and ground sensors is an increasing source of atmospheric data, none of these systems can match the vertical resolution (30 m (98 ft) or less) and altitude coverage (30 km (19 mi)-RRB- of radiosonde observations, so they remain essential to modern meteorology.

The main ECMWF reanalysis webpage (www.ecmwf.int/research/era) has some information about observations used in ERA - Interim, including a timeline (http://www.ecmwf.int/research/era/do/get/index/29/29?showfile=true) and a complete inventory of radiosonde observations (http://www.ecmwf.int/research/era/do/get/index/29/28).

Specifically, the characteristics of the divergence across the datasets are strongly suggestive that it is an artifact resulting from the data quality of the surface, satellite and / or radiosonde observations.

Where can I find the list of radiosonde station observations used in ERA - Interim?

I can recall being censored off of RealClimate for asking Gavin why NOAA still published radiosonde and satellite observations since 1948 showing that tropospheric humidity did NOT increase with temperature over the long term if these were wrong.

Variations in global - mean temperature are inferred from three different sets of measurements: surface observations, satellite observations, and radiosonde observations.

How, for example, does this incident cast doubt on the findings from satellite data, radiosondes, borehole analysis, glacial melt observations, sea ice melt, sea level rise, proxy reconstructions, permafrost melt and such like, gathered completely independently of the CRU?

• the factors that contribute to uncertainties in the trends inferred from three categories of instrumental measurements — Microwave Sounding Units (MSU) carried aboard National Oceanic and Atmospheric Administration (NOAA) satellites, radiosondes, and surface observations;

The black curve represents surface temperature, and the colored curves represent the temperature of the lower to mid-troposphere as inferred from MSU measurements (red) and radiosonde observations (green).

However, for radiosonde observations, which are irregularly spaced with large gaps over the oceans (Figure 2.6), global - mean temperature is estimated on the basis of those stations operating during the season in question.

Using a longer period would made the match of surface and radiosonde observation to models much worst in the period before 1979.

Updating and improving radiosonde observations, particularly in regions of low temperature and humidity.

Satellite observations provide near - global coverage and thus represent an important source of information over the oceans, where radiosonde observations are scarce, and in the upper troposphere, where radiosonde sensors are often unreliable.

From these daily values the monthly mean zonal wind components were calculated for the levels 70, 50, 40, 30, 20, 15, and 10 hPa and a data set from 1953 to the present was produced by combining the observations of the three radiosonde stations Canton Island (closed 1967), Gan / Maledive Islands (closed 1975), and Singapore (data file: qbo.dat).

Another point: the reanalysis datasets are anchored to the radiosonde network especially where the density of such observations is high.

Where there is radiosonde profiles of humidity with height, one must consider representativeness or how well the point observation represents the surrounding environment.

However, the radiosonde observations have fully earned their reputation as one of the mainstays of daily weather forecasting work.

By making radiometer observations (giving observed IR flux) simultaneously with nearby radiosonde flights (giving temperature and humidity readings from which Elsasser tables allowed the computation of calculated fluxes) they showed that:
